T0 [tli whom it may conccr'n:

Be it known that we, IRA TEETER and BY- RoN E. SLY, citizens of theUnited States, residing in W'atertown, in the county of Jefierson andState of New York, have invented new and useful Improveinents in Springsfor Carriage-Cushions, Beds, Mattresses, &c., of which the following isa specification.

Our invention relates to Springs adapted to be used in cushions, beds,lnattresses, &c.

Our objectis to produce an ilnproved spring for cushions, beds,mattresses, the., consisting of a series of top cross-bars and a seriesof bottom cross-bars connected by helices in parallel, Vertical, andhorizontal planes, each cross-bar having a central eye and allconstructed from a single piece of Wire, whereby said cross-bars andhelices are continuously connected, the upper cross-bars being supportedyieldingly by the helices and lower cross-bars, and the upper` and lowercrossbars are connected and supported by transverse bars insertedthrough the eyes aforesaid. It is constructed as follows, referencebeing had to the accompanying drawings, in which- Figure 1 is a sideelevation of an upper and a lower cross-bar, the intermediate helices,and the eyes in said cross-bars. Fg. 2 is a top plan of a cushion, bed,or mattress having three longitudinal series o f Springs, trans- Verseconnecting-bars, and a box orinclosing frame. Fig. 3 is an end elevationof a cushion with upholstery upon said upper cross-bars.

A Wire of suitable shape in cross-section is bent by any suitable meansor devices, so as to create the helices a and a', the upper crossbarconnecting two of the helices a, the lower cross-bar connecting two ofthe lower helices a', each of said cross-bars being also bentintermediately to form an eye b. The helices a are in pairs in parallel,Vertical, and horizontal planes, and the helices a' are in a horizontalplane intermediate to the planes of the Serial No. 695,104. (No model.)

sides of the transverse bars by the alternate winding of the helices atthe opposite ends of said cross-bars. It will be seen that a springhaving these helices and these crossbars connecting them can be made ofany length desired from a single piece of wire, said springs being shownin Fig. 1 as each extending the entire length of the frame or box c, andthat the eyes in the cross-bars can be omitted and slats can be securedthereto by bolts or staples or by any other ordinary means. It will bealso seen that this spring is substantially elliptic in cross-section,having a rentering angle at each end and three helices at the apices ofthe respective angles, and that in top plan these sets of three helicesare in Vertical parallel planes, one set diagonal to the set or set-s towhich it is connected."

What we claim as our invention, and desire to secure by Letters Patent,is-- A spring for cushions, &c., consisting of a Wire bent to form upperand lower cross-bars with central eyes, helices at the extremities ofsaid bars, a rentering angle between said helices and other helices atthe apices of said angles, said eyes being in parallel, Vertical andhorizontal planes, and said helices being arranged in sets of threealternately on opposite sides of said eyes, and being in parallelVertical and horizontal planes, and parallel bars through said eyes.
